Select the correct answerThe arithmetic mean of the following numbers 1, 2, 2, 3, 3, 3, 4, 4, 4, 4, 5, 5, 5, 5, 5, 6, 6, 6, 6, 6, 6 and 7, 7, 7, 7, 7, 7, 7 is?Options541420

To find the arithmetic mean (also known as the average), you need to add up all the numbers and then divide by the quantity of numbers.

Here are the steps:

1. Add up all the numbers: 1+2+2+3+3+3+4+4+4+4+5+5+5+5+5+6+6+6+6+6+6+7+7+7+7+7+7+7 = 119
2. Count the quantity of numbers: There are 27 numbers.
3. Divide the sum by the quantity: 119 ÷ 27 = 4.407407407407407
